THOMAS POYSER, OF SAN FRANCISCO, CALIFORNIA.

PAlNT-BREAMER.

SPECIFICATION forming part of Letters Patent No. 324,163, dated August11, 1885.

' Application filed July 25, was.

- To all whom it may concern.-

Be it known that I, THOMAS POYSER, a citizen of the United States,residing in the city and county of San Francisco, and State ofCalifornia, have invented a new and useful Improvement in Self-ActingBlow-Pipe Lamp and Paint-Burner, of which the following is aspecification.

My invention relates to improvements in blow-pipe lamps in which the gasis generated by heat created bya heated rod connecting with agas-chamber in the interior of the can holding the general supply ofcamphine, alcohol, benzine, or other gas-generating substance. It willbe more fully understood by reference to the accompanying drawings, inwhich-'- Figure l is a perspective view of the lamp with a portion ofthe draft-chimney cut out. Fig. 2 is a cross-section cut verticallythrough the center of the same. Fig. 3 is a plan view. Fig. 4 is aperspective of the gas-generating and flame and heat regulatinggage-rod. Fig. 5 is a cross'section of the lamp, showing the wick-tubewhen placed in the center of the can, and the tube bent to take up thefluid when but little remains in the can, and is a substitute for thestraight tube placed. at the side of the can, as shown in Figs. 1 and 2.

The following is the construction of the same:

A represents a tight vessel or can; B, the wick-tube or chimney; C, thecap of the wicktube; E, thecombustion-chamber; G, the gasgenerating andflame and heat regulating gagerod.

H is the opening for filling the can.

J represents the gas-tube, which in Fig. 2 is shown as beingstraight,while in Fig. 5 it is shown curved at its lower end.

L represents the regulating groove or slot in the rod G. The rod issometimes constructed with the extension M, and generally so where nowick is employed, as shown in Figs. 2 and 5.

O represents the draft-opening or air sup ply.

The form of the can, wick-tube, and combustion-chamber is the same asthat employed in my improvement patented b01116 under date of May2,1882, and numbered 257 ,380.

(No model.)

- I employ the rod Gto generate gas and regulate the amount of flame andheat.

The following is the operation of the same: The can being filled withany suitable burning fluid, when there is a wick the fluid is drawn up,and passing out through the groove L, may be lighted, but'where there isno wick the can is sufficiently inverted and the rod G turned out orunscrewed sufficiently to allow a little of the fluid to pass outthrough the slot L, and when lighted the rod G is quickly heated and gasis formed in the gas-tube J or K, and as soon as the can is righted, thegas flows out, creating more intense heat and heating the rod stillmore. When gas is so rapidly generated in the gas-chamber, and thepressure so increased in the can as to require regulation, the same iseffected by screwing the rod G down into the cap 0, and partiallyclosing the opening formed by the slot L. This slot L is generally filedwith a three-cornered file, tapering from the bottom until it runs outas shown in the drawings. By this arrangement the amount of heat andflame can be perfectly regulated by placing a wrench upon the nipple Nand turning the rod G out or in, thus opening or closing the slot L.

WVhen the can is constructed with the tube in the center, then the benttube must be employed, where there is no wick employed to take up thefluid, as the gas is liable to blow out and allow the cooling of theheater when the supply of the fluid is not kept in contact with theheated parts.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

The combination, with a can having the wick-tube B, provided with thecap C. of the chamber E, inclosing the upper end of said cap and havingopenings D, the gas-tube J, separably connected with the wick-tube, therod G, having the groove L, threaded, as shown, said rod being locatedwithin the tube J and extending into the chamber E, and afilling-opening, substantially as set forth.

THOMAS POYSER.
